Bonding in parent, peer, and school domains were compared in a general sample of children and a sample of children of methadone-treated parents. Bivariate comparisons revealed that children of methadone-treated parents had lower SES, and were significantly more likely to smoke cigarettes but not more likely to drink alcohol. Several measures of attachment were significantly different between the two samples across parent, peer, and school domains. Multivariate analyses indicated that the children of methadone-treated parents were more likely to smoke, even after accounting for the effects of demographic and attachment variables. For drinking, sample membership was not found to be significant. Attachment to school decreased the odds of both smoking and drinking in both samples. Peer attachment had no effect on the odds of smoking initiation; however,loyalty to best friend did predict increased odds of drinking initiation. 相似文献

X-ray photoelectron spectroscopy (XPS) is a widely used technique to characterize the surface chemistry of materials. It plays a crucial role in accessing qualitative and quantitative information and in detecting the presence of chemical functional groups on the surface of any material. The forensic methods available to detect and identify elements and organic/inorganic compounds are often destructive, so evidence cannot be re-analyzed. However, XPS allows rapid analysis of samples without damaging them. Recently, an increasing number of forensic researchers have begun to study certain chemical information on fingermarks. In this study, the authors aimed to present the applicability and power of XPS imaging in fingermark analysis which can also provide specific information about the fingermark chemical composition. Herein, monochromated X-ray (Al Kα) spot size was fixed at 50 μm. XPS mapping resulted in the acquisition of spectra at each pixel, in an array of 41 × 30 pixels with a step size of 50 μm. Then, a simple discussion has been made about how the scanned surface spectrum and basic snapshot spectra are used to identify different components at a fingertip of a scanned surface area (~3 mm2). Hence, a fingermark pattern contaminated with caffeine, TiO2, and Pb/PbO deposited on the silicon wafer can be chemically mapped and visualized by XPS using principal component analysis (PCA). Thus, the present study showed the possible applicability of XPS for the identification of illicit drugs of abuse, gunshot residue, and skin care products on latent fingermark by mimicking a crime scene evidence. 相似文献

The need for political parties both to expand their legislativebase by winning elections and to maintain their organizationbetween elections is translated into two kinds of campaign contributionstrategies. Federalism affects how political parties choosebetween the two objectives and their related strategies. Contributionsto Illinois legislative races reveal that expansive strategiesaimed at candidates with reasonable chances of winning are mostprominently used by state organizations. Maintenance strategies,concerned with ensuring a continued party presence, are mostconsistently pursued by local parties. In general, except forthe national parties, differences between Democratic and Republicanorganizations are comparatively minor. 相似文献
